SPECIFICATION forming part of Letters Batent No. 665,707, dated January 8, 1901. Application filed March 19, 1900. Serial No. 9,166. (No modela -To all w7wm it may concern:

Be it known that I, SENECA H. TROMAN- HAUSER, of the city of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Fire-Escapes, of which the following isa specification.

The invention relates to fire-escapes; and one object of the invention is to provide horizontally-adjustable means attached to the outer walls of oiee or apartment buildings or hotels to permit the escape, in case of fire, of

' the occupants of any office or room on any door which, owing to the height of the building or for any other reason, cannot be reached by a ladder.

A further object is to provide means whereby books and merchandise of various kinds may be quickly and safely removed from the upper floors of the burning building.

A further object is to provide means for quickly elevating one or more fire-hose to the top of a building.

The invention consists generally in various constructions and combinations, all as bereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective of an office or apartment building a plan view o't' the same.

with myirnproved {ire-escape attached thereto. Fig. 2 is a sectional view showing the car or cage, the track supporting the same, and the conduit at the base of the building. Fig. 3 is a side elevation of the car, the supporting-track, and the conduit-rail. Fig. 4 is a side elevation of the truck or carriage supported at the top of the building. Fig. 5 is Fig. 6 is a sectional View on the line u; a: of Fig. 5. Fig. 7 is a side elevation of the carriage or truck provided in the ronduit. Fig. Sis a plan view ofthe same. Fig. is an end View. Fig. l() is a vertical section of the cage or car. Fig. 11 is a horizontal section on the line 'y y of Fig. 10. Fig. 12 is a detail of the guide on the side of the elevator-car.

he apparatus which I have herein shown and described is designed particularly for use in connection with very high buildings, the upper floors of which frequently cannot be reached by ladders, to be permanently attached to the building and ready for use at a frame, I provide momenifs notice. The dre-escapes in general use on the outer walls of buildings are usually located at the end of a hall or corridor and are frequently inaccessible to the occupants 0f rooms at a little distance therefrom on the same door owing to the hall being filled with smoke or certain of the rooms cut cit from the main hall leading to the fire-escape by the progress ot the lire. To obviate this diflicnltyand render the tire-escape accessible from any room in the buildin'g,I prefer to make it horizontally as well as vertically adjustable, and to this end I provide a continuous track running around the building on the outside upon which the ele-rater car orcage is supported. In Fig. 1, I have shown the track supported at the top ot' the building,said track consisting, preferably, of Z-bars 2, bolted secu rely to I-beams 3, arranged at intervals on the roof of the building and overhanging its walls. The inwardly-turned danges 4. at the lower edges ofthe Z-bars form a continuons track around the building, and resting upon these fianges, which are spaced from each other, is a truck or carriage comprising an elongated frame 5, the axles 6 loosely mounted therein,- and the wheels and 8 secured on said axles.' I prefer to provide sheaves 9 on the wheels 8 for the purpose hereinafter described, and I also provide large sheaves 10, loosely mounted on the axles 6 within the frame 5, and between said sheaves, connecting the sides of the bolts 1l, which'prevent the frame from spreading and the cable from accidentally slipping ed the sheaves. In the sidewalk, near the base ofthe building, I provide a conduit running entirely around the building, wherein I arrange at intervals yokes or knees l2, bolted securely to the bottom of the conduit and supporting parallel bars 13, arranged'substantially on a level with the sidewalk and ,forming a track for the conduit car or carriage. This car comprises a casing or frame 1-1, wherein axles 15 and 1G are mounted, provided with wheels 17 and 18, secured thereon. A sheave li) is loosely mounted' ou the axle l5, and a tongue ZOis provided ou v IOO l swinging away fromthe 'windowas the econ-- pass over the piate info.

vided on the axle 22, projecting up through the slot ,in 'the conduit and having a hole 25 anda pin 26 to rest upon the top of the rails. At the 10p of the frame 14.- I Aprefer to provide a bracket 27, wherein a sheave 2S is mounted with its axissubstantially at right angles to that of the sheave 19.

The cage or car which I prefer to use in.l

connection with the apparatus heretoforedescribed consists of a box 29, of wood or metal, as preferred, preferably rectangular in form, having a' closed top and a door 3Q-in one of its side Walls. I prefer` to provide a large opening 31 in the side of the cage next tothe windows of the building, and over said opening, hinged to the'loor of the car, Iprovide a plate 32, having side' boards 33 and `provided with a cord 34, passing over a pulley 35 andc'onnected toacounterbal'ance 36. A liange 37 is provided on the outer end of lthe plate 32 to drop over the inner edge of the window-sill and hold the car tov prevent its pants of the roomv the car. i l

Various means may be employed for rais-4 ing and lowering the car;bu`t I prefer to provide the mechanism herein shown, which consiuts in attaching a cable'38 to the link 24 and passing the same between the idler rollers 39, mounted in the brackets 40, secured to the side walls of the car upon each side, preferably at the top'and bottom nf the saine. vFrom the' idle rolls the cable passes up over one of the sheaves 10 on the frame 5 and down to a sheave 41', provided on a bail 42 on the top of thc car. From the sheavc 41 l the cable passes up'over the second sheave 10 and down between the idle rolls on the oppo-` site side of the car fronit'lie starting-point of the cable to the sheave 19 in the conduit and from thence over the sheave 28 to a suitable hoisting-engine 13.- This originel prefer to make an adjunct of the fire-department parat-us, to be kept in the engine-housc ready" for use whenever there is a tire in a large building t'nat is equipped with my improved life-saving,r apparatus.

By arranging the cable in the manner here- I tofore described l am able to utilizeit to raise and lower the car and at the same time act as aguide for tbe car to prevent it from sway ing or swinging from side to side and striking the walls of the building; during its ascent or descent and causing damage to the car or injury to its occupants.

As heretofore described, the track at thev top of the building. and the conduit below are contin nous to permit the eleyating apparatus to be adjusted in front of any Window in the building, and in order that the apparatus may be properly adjusted before the hoisting mechanism is put into operation I prefer io provide an endless cable 4A, passing over tbc siieav i) and down vthrough and under the bottoni oi' the car, assnown in Fig. 3l, by means ci which the operator can move 'the appara- -by the trucks bearing upon the under side elf one rail andnpon the upper side of' the opposite rail.

If desired, the apparatus may be used lor raising a lire-bose tothe top of a building', as' shown-in Fig. l, wherein the bose is'represented as inserted through a hole in the bottoni of the car andbeiug raised therewith to the top of the building. This feature of the invention will be found lo be of great advantage for elevating re-hose to the upper stoladdersor where .a considerable amount. of time would be wasted in dragging the hose up a ladder or astairway on the inside of the building, 'l

When not in use, 'the apparatus may be moved around 'to the allcyside 0f the .building and thecar raised to the top of Athe blank wall, where it will vbe protected by the cornice and not oier any 'obstruction to the vie W from the Windows or detract from the ornamental appearance of the buildinig'.
